See where the Character Butterface (and the book) has turned up over the years. Please leave any additions in the comments and someone will add it in.
Butterface first appeared in the novel by the same title written by Callie Press. She was an homage to the Cthulhu legend of Narlyathotep, the swirling chaos created by H.P. Lovecraft. She was a legend boys told around Halloween about a gorgeous woman who would seduce you to steal your semen for universe building. Sex with her sealed your doom. Later Moctezuma Johnson has his heroine face her in an epic clash while the Five Hive is on Alien Relish to restore lust and procreation to the universe.
